Subject: [PATCH v6 07/14] ARM: ux500: use remapped PPI interrupts for local timer
Date: Fri, 3 Jun 2011 15:15:51 +0100 [thread overview]
Message-ID: <1307110558-29710-8-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1307110558-29710-1-git-send-email-marc.zyngier@arm.com>
Use the normal interrupt scheme for the local timers by using
a remapped PPI interrupt.
